fix(buildGo): Update buildGo.proto for compatibility with external

Browse source 
Changes in the structure of buildGo.external meant that the package
layout for the protobuf library is now slightly different.

`proto` has been amended to work with the new structure. Callers of
buildGo.proto do not need to be updated (i.e. the example still
works).
